Have you checked the CPU fan and heat exchanger. The heat exchanger (metal
grid) that sits on top of the process and then the fan fixes onto the heat
exchanger is notorious for gathering dust. If there is a lot of dust hanging
around the heat exchanger this will hold the heat and heat will not be
dissipated efficiently from the CPU. Also check the fan blades to see if
they are holding accumulated dust. If they are this may be slowing the fan
speed down. If dust has accumulated be careful attempting to remove it
because you can damage motherboard components. Compressed air is probably
the best, but as you are a poor student this will be too expensive. An
alternative is go borrow your grilfriends makeup brush. You know the one it
looks like the type of brushes the forensic guys use to dust for finger
prints, and gently run that over the fan and heat exchanger to remove the
dust. Finally take a deep breath and blow the dust away. Many people use the
vacuum cleaner, but you must be careful.
Another area to check is the power supply unit. The PSU uses a fan to keep
it cool. As a result the dust in the air is pulled from the bottom of your
pc through the PSU and out again just like a chimney. This fan can also get
laden with dust. One word of warning. The PSU fan is inside the PSU unit.
*Do Not* open the unit. Simply vacuum the dust away - very carefully.
